This report describes the effort to design, fabricate and test a digitizing cursor with integral line centering capability. The resultant cursor is transmissive in nature utilizing a linear photodiode array, an optical system and array signal processing electronics. Processor output is a binary count representing position of the image traced feature on the array. A computer algorithm uses the information as a corrective term to yield accurate coordinate data. Computer-generated rotational commands serve to continuously position the array to be orthogonal to the feature to ensure maximum accuracy in tracing features containing curvatures or forming closed contours. Accuracy of or - .003 inch is obtainable in digitizing with the cursor. Author
